Manan Fault Evolution And Its Oil And Gas Sense In Markit Slope

In this thesis, take full advantage of the latest drilling of pre-project group research and exploration and Development Research Institute, Earthquake basis of the results on the use of regional geological, geophysical, drilling, seismic, stratigraphic, modern geology, system theory, activity theory and other advancedsupport the theory as the theoretical evolution of the main line, to construct the profile recovery, fracture development, balanced profile evolution, the inclined shear restoration techniques as a means to analyze the characteristics of fracture section of the Markit slope Manan region, the distribution characteristics of the fine portrait of the main faultand evolution of the mode. Achieved to recognize:(1) Manan fracture plane is divided into west, central, eastern segment, Yubei fracture is divided into the south, central, north segment. Section fracture Manan, including the basement involved tectonic features and the cap slipping structural characteristics including positive flower structure characteristics, basement-involved structural features and cover slipping structural characteristics, while Yubei fracture fracture of, which, Yubei, the northern section of the depth of overlay and structural characteristics. Manan, Yubei fracture of the main fault developed on the hanging derived fracture, such as Manan on the2nd fracture, Yubei, on the2nd fracture. These faults came together to form the eastern part of the Markit slope Manan fault zone.(2) The paper pointed out that Manan region fracture contains three types of activities, combined with the evolution of the paleostress background, summary of the Manan fault zone five major evolutionary stage:①Sinian-Early Ordovician Tao tension-stretching developmental stages;②Silurian World Reversible-thrust faults in the developmental stage;③Early Carboniferous, the world weak squeeze involvement of the inherited base and cap slippage thrust fault development stage; as early as Permian;④The end of" Y" or anti-Y "-shaped basement-involved style and cap slippage-type reverse thrust developmental stages;⑤Early Jurassic-Holocene: not activities. Jade North has six evolution stages:①Sinian-Early Ordovician of the world stretching-stretching developmental stages;②The middle Silurian the world go sliding pressure torsional fracture developmental stages;③Early Carboniferous,"Y" or against "font basement-involved style and cap slippage type reverse thrust developmental stages;④The end of uplift in the Early Carboniferous uplift and erosion;⑤The late Carboniferous weak squeeze basement-involved, and the cap slippage thrust fault development stage of succession;⑥The-Holocene telogen phase of the end of the Early Permian.(3) On the basis of vertical and horizontal oil and gas shows statistics Manan differences①fault controlled reservoir facies development;②fracture control the types of traps;③fault controlled hydrocarbon migration and accumulation and preservation of the fracture control accumulation mode.
